Specification of Letters Patent.

Patented Aug. 5,1913.

Application filed July 25, 1912. Serial No. 711,594.

To all whom it may concern:

Be it known that I, LoUIs RICHARD SCHMIDT, a citizen of the UnitedStates, residing at San Luis Obispo, in the county of San Luis Obispoand State of California, have invented certain new and usefulImprovements in Stamps, of which the following is a specification,reference being had to the accompanying drawings.

My invention relates to new and useful improvements in hand stamps andmore particularly to an improvement on my former application filedNovember 20th, 1911, Serial Number 661,275, and allowed June 18th, 1912,and the primary object of the invention is to provide a means wherebythe fingers of the operator will not contact with the type bands in theoperation thereof.

A further object of the invention resides in providing an improved framefor the device to allow the operating parts to be readily and quicklyremoved and replaced therein when it is necessary to change the typebands of the device and a still further object is to provide meanswhereby the operating mechanism of the type bands is securely held inposition, under tension of said type bands.

Still another object of the invention resides in providing a devicewhich is extremelv simple and durable in construction, inexpensive tomanufacture and one which will be very efficient and useful inoperation. I

\Vith these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawings forming a part of this application,Figure 1. is a front elevation of the device. Fig. 2 is a verticalsection therethrough. Fig. 3 is a side elevation of the same. Fig. i isan opposite side elevation of the device with parts in section. Fig. 5is a perspective view of the frame member with the operating mechanismremoved. Fig. 6 is a similar view of the bottom or pressure plateremoved. Fig. 7 is a vertical section through a slightly modified formof the invention; and Fig. 8 is a side elevation of the latter form.

In describing my invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which 1 indicates a frame of substantiallyinverted U-shape design, such as is ordinarily used in devices of thischaracter, the base or horizontal portion thereof being of considerablewidth and somewhat arcuate in design and secured to said latter portion,through any desired means, is a handle mem her 2. The arms of thesubstantially inverted U-shape frame 1, are cut-away or slotted from oneside edge thereof and the slotted portion in one arm terminates in thesmall notch 3, while the other is formed into a larger notch or cavity 4and adapted to be disposed through said notches 3 and 4:, is a shaft 5.The one end of said shaft which is adapted to be received, in thesmaller notch 3, has provided thereon, im mediately adjacent the endthereof, a spoollike sleeve or cylinder 6, the one end of which isprovided with a peripheral flange or the like 7 adapted to abut theinner face of the adjacent arm of said frame 1 and the opposite end ofsaid shaft 5 which extends considerably beyond the opposite arm of theframe is also provided with a sleeve member 8, a portion of which ismilled to be hand operated.

Telescoping the shaft 5 and extending for the greater portion of itslength is a tubular shaft 9, the one end of which has mounted thereon anadditional sleeve or cylinder 10, the ends of which are provided withperipheral flanges 11 one of which is adapted to abut the one end of thesleeve or cylinder 6 and the opposite end of said tubular shaft 9 isprovided with a sleeve member 12 which abuts the sleeve member 8 of theshaft 5 and is slightly larger than the latter, but also milled to bereadily operated by the hand. Telescoping the tubular shaft 9 is anadditional shaft 13, which is provided on one end thereof with thecylinder 14, having the peripheral flange 15 at one end thereof, and theopposite end of said shaft 13 is provided with a sleeve 16, similar tothe sleeve 12, but slightly-larger than the same. This cylinder orsleeve-like member 1 1 abuts the cylinder 10, while the sleeve 16 abutsthe sleeve 12 and mounted on said tubular shaft 13 is an additionalsleeve-like portion or shaft 17 which has a cylinder 18 and asleeve-like portion 19 formed thereon. The

cylinder 18 at one end thereof abuts the peripheral flange of thecylinder 14, and the opposite end of the same is also provided with aperipheral flange 20 which contacts lightly with the inner face of thearm of said frame 1 having the notch at therein. The sleeve-like member19 which has a milled portion thereon slightly larger than the adjacentmilled portion of the sleeve 16, is spaced slightly from the cylinder 18and the space between the same is provided with an annular groove 21which is snugly disposed in the enlarged notch 4 in the one arm of theframe 1. From this construction, it will be seen that the variouscylinders may be independently rotated by the graduated portions of thesleeves mounted on that portion of the shaft 5, which projects beyondthe one side of the frame 1.

The sleeve or cylindrical members 6, 10, 14 and 18 are each of the samediameter, but may be of varied lengths, as desired, and extending overeach of the same is an endless elastic type band 22. These bands arealso extended over a bottom. of pressure plate 28 which ischannel-shaped in design and has the ends thereof provided with upstanding lugs 24 which are spaced slightly from the ends of the sideflanges of said plate. The free ends of the sides of the frame 1 areprovided with notches 25 which are adapted to receive therein portionsof the lugs 24:, the upstanding portions of said lugs being disposed onthe outer faces of said side arms and as said bands 22 are extended overthis plate 23, under tension, it will be seen that said plate will beheld securely to the frame and the shaft with parts carried thereonsecurely held to said frame.

In practice, assuming that the device is set up for use, should it bedesired to use the same, the operating sleeve members extending to theone side of the frame 1, are rotated until the desired characters on thebands 22, which are correspondingly caused to rotate, are positioned onthe under face of the bottom plate 23. The bands may then be inked froma pad, as usual and used as desired. It Will be seen, however, thatshould it be desired to change certain characters on the bands, saidbands may be independently operated in such a manner that the fingers ofthe operator will not contact with said bands. Should it be foundnecessary to remove one of the type bands for any reason whatsoever, itwill be seen that the operating mechanism may be readily moved from theframe by merely forcing upwardly and outwardly upon the extended end ofthe shaft 5 so as to remove the annular groove 21, in the member 17,from its engagement in the enlarged notch 41. With this portion of theoperating mechanism removed from the notch 41-, it will be readily seenthat the opposite end of the shaft may be readily removed from the notch3, which will allow the bottom plate 23 to be disengaged from the frame1, thereby permitting the desired band to be removed from the respectivecylinder. From this description of the manner of removing the operatingmechanism, from the f nine of the device, the manner of assembling thedevice will be obvious.

In Figs. 7 and 8, I have shown a slightly modified form of the inventionwherein an inverted U-shaped frame 26 having the handle 27 thereon hasthe arms of the same slotted or cut-away as shown at 28, which slottedportions terminate in alining notches 29 identical with the notch 3 inthe one arm of the frame 1, as shown in the other form. A shaft 30extending transversely of the frame 26 is adapted to be removablymounted in the notch 29 and has a spool-like sleeve member 31 carried onthe one end of the same, the peripheral flanges of said spoollike sleevemember being adapted to be disposed on opposite faces of one of the armsof said frame 26. Loosely mounted on said shaft 30 are a plurality ofcylinders or sleeve-like members 32 which abut one another andcompletely fill the space between the arms of the frame 1. The one endof each of said cylinders or sleeve-like members 32 is provided with anenlarged disk or the like 33, the peripheral edge of which iscorrugated, milled or otherwise roughened to be readily grasped by thehands of the operator and rotated, whereby the respective cylinder towhich the same is secured may be rotated on the shaft 30. These disks33, while forming a means whereby the respec tive cylinders orsleeve-like members 32 may be rotated on the shaft also form spacingmeans between said cylinders and extended over each of said cylinders,is an endless elastic type band These type bands 3% are also extendedover a bottom plate 35, identical with the bottom plate 23 in the otherform and as said bottom plate and shaft are held in the frame, undertension, of said type bands, it will be appreciated that the same willbe securely held in position and may be quickly removed, when desired. I

From the foregoing it will be seen that I have provided a device whichis extremely simple and durable in construction, inexpensive tomanufacture and one which will be very efficient and useful in operationand while I have particularly described the ele ments best adapted toperform the funo tions set forth, it is obvious that various changes inform, proportion and in the minor details of construction may beresorted to without departing from the spirit or sacrificing any of theprinciples of the invention.
